In regard to the movie TRON, as someone stated earlier, I believe the work for it was indeed done on a Cray. The F1 was actually used to do the computer graphics for a Disney movie called "Flight of the Navigator". There's a really nifty site about it at the following URL. http://vhost2.zfx.com/~dave/f1.html Kind regards, Sean BTW: Pete, are those EISA cards still up for grabs? I might be willing to take them... I could always hope that NetBSD will support my Jensen more effectively in the future and that I may be able to put some of them to interesting use! -- Sean Caron http://www.diablonet.net scaron(a)engin.umich.edu root(a)diablonet.net

Sure they suck, on that mangy 486... ;) Most graphics problems under Windows Xp and 2000 can ultimately be traced to poorly-written video card drivers... the NVidia and TNT, Voodoo, Banshee, and other 3D-focused cards are the worst.

C64View PC/Mac C64 image viewer

by spectre＠stockholm.ptloma.edu

After a long, long delay, C64View, the venerable PC C64 image viewer utility, finally been updated (to version 0.5.x). A new Power Macintosh port is available as well! This version fixes a few bugs in the old 0.499.x, as well as adding support for generic 8K hires bitmaps and the ability to save the image as a .pict (Macintosh version only). C64View can thus view DOODLE!, KoalaPainter, Print Shop Screen Magic, Flexidraw, 1K colourmap and 8K bitmap files. The PC version runs on MS-DOS 5.0 or higher, as well as Windows 95/98/ME/NT. The Mac version runs on any Power Mac with CarbonLib (prefer OS 8.6 or higher). C64View is freeware.

OT? Apple Stylewriter problems (longish)

by mtapley＠swri.edu

All, I'm having and creating trouble with my Stylewriter 1. Problem appeared about a month ago. One row of pixels consistently failed to print. This happened on multiple ink-jet cartridges and after attempting to clean the cartridge (by soaking in 95% propan-2-ol, or isopropyl as the label says). So I opened the thing up, breaking only a few minor plastic latch pieces on the way (and hey, I glued them back - good as new! :-) ). I ohmed out the flex cable from the circuit board up to the print head. The left 25 pads on the circuit board end of the cable conduct with no more than a few ohms up to the 25 contacts where the print cartridge attaches. So I reassembled enough to let it print while I could still see the flex cable. Still missing a row of pixels. The left 2 of the wide traces and the right 2 of the wide traces connect to pins on the flex-cable connector which show about 3V rms while printing and zero while not printing. 3V rms means that's about what my analog Volt-Ohm-meter needle showed while printing a solid black block. But I could not get to the middle 4 connectors because the ribbon cable was in the way. So I took out the circuit board, flipped it over, reconnected all the cables (right way around? I thought so ....) and tried to print again. The printer powered up, but as it tried to print the first time, the power supply (wall-wart) quit working. This was also around the time my VM probe slipped off one of the pins on the row of transistors I was trying to check :-(. Did I short something bad, or mis-connect the ribbon cables and do something equally bad? The power supply (wall-wart) now puts out about 0.2 V (again on my analog VM), vs. the 10 or 11 it used to do. So, questions: 1) Is my (original) problem likely to be one of those transistors? There's a row of 9 of them, right next to the flex-cable connector, with big fat traces leading to doubled pins on the connector and thence to nice wide traces on the flex cable. They are labelled B1243 (I think). 2) What's a less destructive way of telling which one? - Or is it better to just replace all of them? 3) How, short of a large hammer, do I get the power supply opened up? 4) What am I likely to find toasted in there? More details available on request. I'm in digest mode, so it'll be a one-day cycle unless you email me directly (mtapley(a)swri.edu), and still probably a day because I'll read email at work and the busted machine is at home. Apologies if this is not on-topic. Thanks in advance for any help or pointers. - Mark

When I wrote this earlier in the evening, I only had the original disks. After some considerable web searching I found a reference to the P390 ftp site. The reference was not I hasten to add, to be found anywhere on IBM's support pages. The docs in the ftp site don't specifically endorse AIX5L, but it did say the system dumps I've been having were common when upgrading to 4.3.3. And I should therefore upgrade the r390 binaries I had. Low and behold there they were on an anonymous FTP server. And shockingly enough I am now sitting in front of an MVS installation that no longer system dumps all over me. Technically it still doesn't IPL, but I'm positively gleeful anyway.

The cable was near-zero resistance,in a write-head position about halfway across the page, so I don't think that's it.

I think 8, but don't have any good evidence for that other than the row of 9 (what look like) driver transistors, of which one is slightly offset. 8 pixels would just about square with the width of the missing row vs. the distance between rows when I try to print a solid black block, but 9 might work too. The printer is 1991-93 era (about?) and was 1st generation ink-jet for Apple. I guessed 8 pixels based on the number of big wide traces coming across the ribbon cable and on the theory that it takes one big wide trace per pixel.

No number. It's a retail product that's been around for decades (Araldite was invented by Aero Research in the UK and came to fame during WW2; it was sold to Ciba after the war). We can get the numbered types as well, but they're less common; I'd need to go to an engineering (or electronics or microscopy) supplier for most of them. Unfortunately that means I can't tell you what the equivalent number version would be in the States :-( The standard stuff is a 50:50 mix, comes in blue and yellow tubes, and like all epoxies is thermoplastic. It softens at around 150 deg.C. You can vary the mix slightly to make it a little more or less rigid/hard. The normal mix sands/files well.

IBM R390 IPL woes...

by out2sea00＠yahoo.com

Folks -- Tomorrow I pick up the IBM 5362. But I have another obscure piece of hardware I'm playing with. Anyone ever hear of an IBM R390. This is an RS/6000 with an SBC mainframe in the MCA. The share IO, but nothing else. I've been rebuilding this thing as my UNIX workstation at the office. The problem I'm having is getting the mainframe to IPL (of course). This is probably, because -- fool that I am -- I FDISK'd the box and upgraded to AIX5L. Does anyone know if there's a binary compatibility issue with the mainframe board's system files, and the newer AIX binary set?

Prophylactic replacement of electrolytic capacitors?

by kapteynr＠cboe.com

Tony: You first question is answered by your second question. The reason that I propose to "insulate the computer from the world" is to solve the first problem that you pointed out: "applying the reforming voltage ... to random points in the logic" If the computer itself was "insulated from the world", the chasis would be able to float so that no actual voltage was applied to any circuit other than the capacitor being reformed. You would need to be sure that you did not even touch the computer during the process. If my theory actually works -- it could save a lot of trouble for computer restorers. My assumption is that the two sides of the capacitor are isolated from each other. This seems like a reasonable assumption to me. But, just in case, I thought I should check with those of you that might have more experience rehabilitating old computers. Perhaps I just need to find something less precious than my Altair to try it out on .... Why don't I want to unsolder the capacitors ? My experience is that I can do a lot of damage unsoldering things. My soldering skills are not as good as they were when I put the Altair together 25 years ago. My fingers and eyes do not seem to work as well as they did back then either. Perhaps I just need to get myself one of those new high-tech temperature controlled soldering irons. Tony: Reading your later messages, I notice that you recommended using a VOM meter in the Ohms mode to test the caps. I have always avoided the Ohms mode of a VOM when working with TTL circuits. The VOM applies a voltage to its test leads when it is in Ohms mode. As I understand it, delicate circuits an actually be damaged by these meters. I have not worked with hardware in years though. Maybe the modern VOM meters are safe. -Rob -----Original Message----- From: Tony Duell [SMTP:ard@p850ug1.demon.co.uk] Sent: Monday, January 14, 2002 6:09 PM To: classiccmp(a)classiccmp.org Subject: Re: Prophylactic replacement of electrolytic capacitors? > > I have not yet tried this yet -- > In theory, electrolytics can be re-formed. > There is a very thin aluminum oxide layer that disappears after a long time. > Running current through the cap will rebuild the insulating layer > until current will no longer go through it. OK, yes, reforming can work... > > I want to reform the original capacitors in my Altair "in place" -- > i.e., without unsoldering them. Why do you not want to desolder them? It'll do a lot less damage than applying the reforming voltage (a little above the working voltage of the cap) to random points in the logic. For example, there are likely to be some 16V electrolytics between the +5V line and ground. Do you seriously want to try running TTL at 18V?

Nope, original Araldite (sets in about an hour and cures fully in 8-24 hours, faster at higher temperatures) and Araldite Rapid (sets in 5-10 minutes, and cures in about an hour) are both clear-to-amber epoxy resins.

Prophylactic replacement of electrolytic capacitors?

The quick and dirty test is to use an *analogue* meter (what Americans used to call a VOM, not a VTVM) on the ohms range across the capacitor. The needle should flick violently across (indicating zero or low resistance) and then fall quickly (at first) as the capacitor charges (and the current drops). Ideally it should end up showing virtually infinite resistance. It needs a bit of experience, though, as the violence of the flick depends on ESR and capacitance, and there tends to be some leakage in an electrolytic so the final reading is often not zero current. It may be worth trying if you have a known-good capacitor of similar voltage and capacitance to compare. A digital multimeter is rarely any use for this, though. The response of the meter is just too slow; by the time it's shown the first reading the event is all but over. Also most DMMs use very low voltages and currents, not enough to give a big electrolytic a good fright. -- Pete Peter Turnbull Network Manager University of York

You're right; the 68010 saves slightly more state on the stack than the early 68000. I have a feeling that was fixed in later 68000; some traps save more state than others. You can't get 68010s any more, unless you can find old stock somewhere :-( You can still get 68000s and 68020s. -- Pete Peter Turnbull Network Manager University of York

Homemade VCDs or cheap VCDs being the biggest offenders. I can ask him what model it is if you are interested. -chris <http://www.mythtech.net>

Zebra system

by mythtech＠Mac.com

in case anyone cared (who knows with this group sometimes) The Zebra computers I had that ran Pick were "Zebra 2500" made by General Automation. Now that I am back in my office, I just looked at the manuals under my desk. If anyone wants them, the manuals are available (I don't really want them for anything). Best offer takes them, minimum offer of cost of shipping (from Ridgewood, NJ 07450, or you can pick them up). There are two 3" binders with assorted smaller manuals clipped into them. Most of the manuals seem to be about Pick more than about the Zebra machines. If anyone wants a list of what the smaller manuals are, let me know and I can flip thru and write down the names. -chris <http://www.mythtech.net>

Available: Commodore 64 with drive

by mythtech＠Mac.com

I have a C-64 here with a floppy drive. No cables of any kind (but I have a call into the guy that gave it to me, to see if he still has the cables). Anyone want it? I don't know it if works, but my friend said it worked when he stopped using it (5+ years ago). It is rather dusty, and was kicking around on his basement floor when I found it and asked if he still wanted it, so who knows the condition now. I don't know the value of such a machine, nor do I think I care... I just want to get rid of it (taking old electronics is an addiction of mine that I need to break since I ran out of room a long time ago). There is a copy of Bank Street Writer sitting in the disk drive. The drive is a 5.25 drive, model number 1541. The stuff is available as a package, or in peices. Best offer gets it (or any part of it), with lowest acceptable offer being cost of shipping (shipping out of Ridgewood, NJ 07450, you can also pick it up if you want). If I can get the power supply and disk drive cable, I will post a note. So to sum up... items available: C-64 5.25 floppy drive model 1541 5.25 original disk for Bank Street Writer -chris <http://www.mythtech.net>

I know that NeXT said it maxes out at 32 MB, but it actually will use 8 MB SIMMs very happily, as long as they are not EDO, and you can then put the SIMMs you "stole" from your slab back in the slab, and you'll be ready to go. (I say this from experience: I have 2 Dimension boards, and they both have 64 MB of RAM, with 8 8MB SIMMs each.) Good luck. PB Schechter

A story

by tarsi＠binhost.com

Hi, folks. A story for you. A long time ago and not so far away, a small town church obtained it's first computer. An IBM PS/2, quite sophisticated for the day. It was in the secretary's office for use of keeping budget and some word processing. As luck would have it, a young boy was around when his father was working on the computer. He must have been around 12 or 13. His father got to work on the computer because he was treasurer. The boy was jealous, a toy! A toy with lights and whirring sounds and computer sophistication, similar to the Apple computers that he had known so well from school. The boy wanted to touch the computer, but knew better. Sort of. The boy touched it once when his father was away and the office was open. He started up the fancy computer and looked as it powered up. He was very impressed. He looked through the manuals. He tried to run some software. He marveled at this wonder of technology. Fast forward to 2002. The same boy and a friend of his had gone to a town quite far from the church to have some Chinese food and catch up with each others' lives. Now being grown up, the boy still had a great liking for old computer toys and things. Being bored, the two friends went to the local Goodwill to look around and see what there was. Back in the corner on a table was a small computer system, quite old. It didn't have much with it, just the computer, a monitor, and a keyboard. However, the boy didn't have this type of computer in his collection yet, so he went to the local ATM and got some cash, came back, and bought the computer. Bring this computer home, it sat in the corner for some time, preempted by some other computer hardware, for the boy had a large collection. One night, being quite productive, the boy decided to boot up this $10 computer and see what was on it. The boy knew very little of what he would find hidden in the secrets of the hard drive of this computer. For the new, fancy computer that the church had purchased and the little boy had marveled over so long ago had served its time, and had been replaced. It went to a number of other people, the files left on its hard drive a testament to the movement of the computer. And eventually, the computer came to be donated to a Goodwill and put up for sale. The boy, Nathan Pralle, found that the computer he had admired so long ago was sitting before him. Indeed, the very first PC he had ever touched, the one at Trinity Lutheran Church in Hampton, IA, and one which had contributed to his becoming a computer programmer, was now sitting on the floor of his very living room, about to become part of his computer collection. An IBM PS/2 Model 30. And now you know the rest of the story. (I love this hobby.) :) Nathan 210 -- ---------------------------------------------- Homepage: http://tarsi.binhost.com binHOST.com: http://www.binhost.com Forever Beyond: http://www.foreverbeyond.org ----------------------------------------------
